Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.

Case 43 — Lume comparison: keep exposure and charging conditions consistent · source wording exercise
Summary draft for “Lume comparison: keep exposure and charging conditions consistent”: the answer addresses “Repeat with equal light source, charging duration, elapsed time and camera…”; the related point is “Treat the comparison…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
Correction note for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: retain the wording beginning “A bright initial glow followed by a steep drop…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
Case 39 — Comparing versions without mixing case sizes · source wording exercise
Clarification for “Comparing versions without mixing case sizes”: the point beginning “List confirmed differences separately from seller descriptions and date the comparison…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: source wording. Retain the source wording beside any paraphrase.
Reader check for “First QC request: the minimum useful information”: distinguish the discussion point “Include complete instrument settings where relevant and say…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “Record the change and the circumstances without treating…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.

Case 37 — Packing photographs: document condition without exposing an address · source wording exercise
Method note for “Packing photographs: document condition without exposing an address”: use “Remove names, addresses, barcodes and tracking tokens from public…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Retain the source wording beside any paraphrase.
Case 13 — QC checklist: prioritise observable faults over pixel hunting
Correction note for “QC checklist: prioritise observable faults over pixel hunting”: retain the wording beginning “Start with function, legibility, assembly and…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
Case 52 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
A dark area appears at an oblique angle in a single photograph. Does that establish a coating difference?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare multiple controlled angles and describe the visible observation without asserting…” as the discussion anchor; no new event or result is supplied.

Case 31 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.
Case 49 — Model comparison: dive bezel action and alignment, how to compare fairly · source wording exercise
Limit of the answer in “Model comparison: dive bezel action and alignment, how to compare fairly”: “Crisp vs mushy is mostly about…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: source wording. Retain the source wording beside any paraphrase.
Case 3 — Service enquiry: information a watchmaker can use
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Exercise RWF-14597/3: address this question within its stated limits.
Case 29 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Case 34 — QC photographs: perspective or a genuinely tilted index?
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
